[PATCH] Use standard_output_file for saved trace file.

[Yao Qi <yao@codesourcery.com>]

Hi,
During the review of CTF patches, Tom pointed out that we should use
standard_output_file for these generated trace files.  I've done that
in my CTF patches, but find my recent commit in gdb.trace/report.exp
doesn't follow this rule.  This patch is to fix it.

gdb/testsuite:

	* gdb.trace/report.exp: Use standard_output_file for saved
	trace file.
